2002 NISSAN XTERRA engine coolant

WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time when
the coolant temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at an authorized NISSAN
dealer.When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for tow-
ing must be followed. Incorrect towing equip-
ment could damage your vehicle. Towing
instructions are available from an authorized
NISSAN dealer. Local service operators are
generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advis-
able to have the service operator carefully
read the following precautions:
WARNING
ONever ride in a vehicle that is being
towed.
ONever get under your vehicle after it
has been lifted by a tow truck.
CAUTION
OWhen towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, dollies
must be used.
OAlways attach safety chains before
towing.

Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
OPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the shift lever
to P (Park).
OBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
ONever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
ONever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.

OIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts, and any other moving parts.
OIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
OAlways wear eye protection when-
ever you work on your vehicle.
OIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
ONever get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
OKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
OOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSAN
dealer because the fuel lines are
under high pressure even when the
engine is off.
CAUTION
ODo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
ONever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is on.
ONever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
OAvoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of ve-
hicle fluid.
This ``Maintenance and do-it-yourself'' sec-
tion gives instructions regarding only those
items which are relatively easy for an owner
to perform.
A genuine NISSAN Service Manual is also
available. See ``Owner's Manual/ServiceManual Order Information'' in the ``Technical
and Consumer Information'' Section.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round,
genuine NISSAN anti-freeze coolant solu-
tion. The anti-freeze solution contains rust
and corrosion inhibitors, therefore additional
engine cooling system additives are not
necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ratio
of 50% Genuine Nissan Anti-freeze
coolant or equivalent and 50% de-
mineralized or distilled water. The use
of other types of coolant solutions may
damage the engine cooling system.

WARNING
ONever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Serious
burns could be caused by high pres-
sure fluid escaping from the radiator.
See precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section of this manual.
OThe radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below the MIN level, add coolant to the
MAX level. If the reservoir tank is empty,
check the coolant level in the radiatorwhen
the engine is cold.If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.
